Answer:
[tex]21\%[/tex]
Step-by-step explanation:
Original dimensions of the rectangle
[tex]l=7\ \text{units}[/tex]
[tex]w=3\ \text{units}[/tex]
Area of the rectangle
[tex]A=7\times 3=21\ \text{units}^2[/tex]
Scale factor = 1.1
New dimensions
[tex]l'=7\times 1.1=7.7\ \text{units}[/tex]
[tex]w'=3\times 1.1=3.3\ \text{units}[/tex]
The new area of the rectangle
[tex]A'=7.7\times 3.3=25.41\ \text{units}^2[/tex]
Percentage change is given by
[tex]\dfrac{A'-A}{A}\times 100\\ =\dfrac{25.41-21}{21}\times 100=21\%[/tex]
The percentage by which the area of the rectangle increases is [tex]21\%[/tex].

Terrance has 12 of the 15 collector's edition books in a series. Keymar has LaTeX: \frac{4}{5}4 5 of the series. Who has more books? Group of answer choices both oof them Terrance keymar
Answer: Both of them
Step-by-step explanation:
There are 15 books in the series.
Terrance has 12 of them and Keymar has 4/5 of them.
The number that Keymar has is:
= 4/5 * 15
= 60/5
= 12 books
They therefore both have the same number of books from the collection.

what's 3x+5y=-7 (show step by step on paper)
Answer:
m=-3/5
Step-by-step explanation:
Simplifying
3x + 5y = 7
Solving
3x + 5y = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
3x + 5y + -5y = 7 + -5y
Combine like terms: 5y + -5y = 0
3x + 0 = 7 + -5y
3x = 7 + -5y
Divide each side by '3'.
x = 2.333333333 + -1.666666667y
Simplifying
x = 2.333333333 + -1.666666667y

2x + 5y = 6
2x = 10 – 3y
Solve the simultaneous equations by substitution
(Sorry all my questions are maths i suck, more to come)
Step-by-step explanation:
Given equations
2x + 5y = 6 .......i)
2x = 10 - 3y...... II)
Putting 2x = 10 - 3y in equation i
10 - 3y + 5y = 6
2y = 6 - 10
2y = - 4
y = - 4 / 2
y = - 2
Now putting y = - 2 in equation ii
2x = 10 - 3 * ( - 2)
2x = 10 + 6
2x = 16
x = 16 / 2
x = 8
So x = 8 and y = - 2
Hope it will help :)❤

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
We have,
She knows that finishing the shed will take 120 work hours.
let n be the number of volunteers.
So, 1/n - 1/(n+1)= 1/120
(n+1-n)/n(n+1)= 1/120
1/n²-n = 1/120
n² - n= 120
n² - n -120= 0
n= 11.46 and n= -10.46
Thus, 12 volunteers already signed up.

Which statements are true about the system of equations? Select all that apply.
Answer:
✔The graph of the system consists of lines that have exactly one point of intersection.
✔The system has no solution
✔The system has exactly one solution.
✔The system has more than one solution.
Step-by-step explanation:
A system of linear equation is known to be a set of one or more linear equations which involve the same set of variables.
A system linear equation can have no solution, exactly one solution or infinitely one solution. When they have one solution, the lines have exactly one point of intersection. When they have no solution, the lines are parallel and when they have more than one solution, the equations are the same.

m=10-(-2)/3-(-1)
m=10+2/3+1
m=12/4
m=3
slope is 3

Find the mean absolute deviation (MAD) of the following data set. Round your answer to two decimal places.
3, 10, 6, 9, 7, 4
Answer:The mean absolute deviation (MAD) of the data set=2.17
Step-by-step explanation:
The mean absolute deviation (MAD) is also called the Mean deviation which tells us the variation and average distance of the mean and each data value in a data set.
Given the data set
3, 10, 6, 9, 7, 4
First find the mean
Mean =Sum of data set / Number of data set
=3+10+ 6 +9 + 7+ 4/ 6 =39/6 = 6.5
Next step is to subtract each data set from the mean and ignoring any negative sign accompanied to find the distance from the mean
Value distance from mean
3, 6.5 -3 3.5
10 6.5 -10 3.5
6, 6.5-6 0.5
9, 6.5 -9 2.5
7, 6.5 -7 0.5
4 6.5 -4 2. 5
Last step is to find the mean of the distances which is
Mean Deviation = (3.5+ 3.5+ 0.5+ 2.5+0.5+ 2.5) / 6
=13/6
=2.166666 rounded up to 2.17
